Riley’s piece is more of a challenge than Reich’s because it is less structured, more mutable and highly shaped by the musical personality of the performers. The 15 talented players in GVSUNME — most of them students — played an engaging version that they made their own with the use of electronics and flourishes like a saxophone solo to open the performance.

Sunday’s concert was a celebration of the release of In C Remixed, GVSUNME’s double-CD recording of In C and 18 remixes by 16 artists. The ensemble’s recording of “In C” clocks in at just over 20 minutes. For Sunday’s concert, the group played for about an hour. That’s the other major variable of the piece — it’s written in such a way that it can be as long or short, within certain limits, as the players want it to be.

With Jad as host and an opening set by the Slow Boys (Todd Reynolds and Michael Lowenstern, who also have remixes on the CD), it’s shaping up to be a memorable evening.

But if you really can’t make it, not to worry. The show is being recorded by WNYC/WQXR and will be available for listening on WQXR’s Q2 stream.

In C Remixed, featuring the GVSU New Music Ensemble and the Slow Boys is at (Le) Poisson Rouge, 158 Bleecker Street, Manhattan. (212) 505-3474. Doors at 6:30 pm, show at 7:30. Click here for more info or here for tickets. $15 in advance.
